Yet, most studies have employed generalized or horsemanship terms in describing conformational traits. Space between the fourth carpal, the third metacarpal, and the fourth metacarpal bones, 7. This can be demonstrated by the red lines in Figure 2. The evaluation of conformation has traditionally been subjective or empirical and remains the primary method of assessment. Balance. The stance of the horse has been identified as a major source of error in conformation assessment, as small changes in limb placement and weight distribution can introduce significant variation in segmental alignment. Attachment of the long lateral ligament of the tibiotarsal joint to the plantar border of the calcaneus A wedge pad also increases ground pressure forces through the heels, which actually reduces heel growth, when the goal should be to promote it. Conditioning a horse properly goes a long way toward delaying the onset of fatigue, and using leg protection can help prevent interference injuries. Shortened stride length and a more jarring gait for a rider. When examining horses for conformation, either when considering a purchase or competing in horse judging contests, it is important to break things down into key principles to avoid becoming overwhelmed when putting the overall picture together. Developing a horses entire body to be strong at the center and balanced from front to back helps overcome many conformational problems.. The entire hindlimb should be bisected evenly in the caudal view. Farrier textbooks suggest and determine excellent conformation as feet, cannon bone and knees Magnusson (1985) showed less variance among judges on overall impressions and type traits. Radiography has also been used to measure joint angles and segment lengths. Selection of a horse in the presence of a less-than-desirable conformation is not always considered unwise. Dynamic conformation. Short-Strided Horses. horse conformation Horse conformation is sometimes described as a complex or polygenic trait. But the front versus rear leg lameness tends to relate to overall horse use. Conformation refers to the shape or structure of a horse, and it can impact a horse's athletic ability. The evaluation of conformation has traditionally been subjective or empirical and remains the primary method of assessment. The stance of the horse has been identified as a major source of error in conformation assessment, as small changes in limb placement and weight distribution can introduce significant variation in segmental alignment. Short-Backed vs. Long-Backed Horses. Tends to wing the feet with potential for interference injury. The back should be one-third of the horses length. One way to measure this angle is to measure down the center of the shoulder blade to the point of the . Lateral tuberosity of the distal end of the radius The general shape or outline of an object, or the arrangement or configuration of parts of an object The hind legs have fewer lameness issues than the front legs because they only carry 40 percent of the horses weight. Join us as we interview leading equine researchers from the University of Kentucky, Problem Solver Series: How to Control Nuisance Birds on Horse Properties. Using shoe branch extensions to attempt to twist a horses toed-in or toed-out conformation to what is considered normal can also create long-term problems, pain, and lameness. Congruent sloping angulation of the shoulder and hip is also desirable, with a proportional length of individual limbs in relation to the height and size of the body (Figure 15-3). These horses can indeed have a conformation fault (a definite twist or deviation of the bones) or they can be compensating . Dorsal edge of the coronary band The set of the neck relative to the shoulder is significantly more important than the length of the neck., Duberstein stresses, Balance and structural correctness have always been two main criteria in judging a horses conformation, and probably for good reason. Whether you are shopping for a new riding prospect or already have a horse, it helps to be able to correctly evaluate conformation. The constant growth of the hoof creates a dynamic relationship between the digital axis and dorsal hoof wall, which suggests that completely straight hoofpastern axes cannot exist over time without natural wear or appropriate trimming (Moleman et al., 2006). A careful examination of the feet of the horse . As a horse comes into the breed ring and stands at the peak of the triangle, the judge has only three minutes to make a total assessment. In Ross MW, Dyson SJ, editors: Diagnosis and management of lameness in the horse, Philadelphia, PA, 2003, WB Saunders, p 21.). Each breed organization has identified its ideal horse. horses have conformation. Some conformational traits are more likely to affect horses soundness and performance depending on the discipline. Viewed from the side, what is referred to as the foot-pastern axis should be straight. However, certain conformational faults such as extreme tarsal angulation (large or small) and tarsal valgus are almost certainly predisposing to injury or lameness in racing events and are best avoided. More than 65% of the traits exhibited large (CV > 10%) phenotypic variation within the sampled population. Prepurchase recommendations and perceived animal value rest highly on this assessment. The entire hindlimb should be bisected evenly in the caudal view (see Figure 15-4). So, it is sensible to avoid conformational problems like being calf-kneed (back at the knee), which potentially exacerbates hyperextension of these joints. The major disadvantages in using these methods are the possible errors introduced by marker placement on skeletal landmarks, particularly in the proximal skeleton, the consequent reliability of findings, and the time required to perform the measurements (Weller et al., 2006a). Subjective assessment of conformation A line dropped from the cranial aspect of the greater tubercle of the humerus (point of the shoulder) should bisect the forelimb in the cranial view. and more. This length should be about 1/3 of the body length. The skeletal format will affect such factors as joint range of motion, limb arc and hoof flight patterns, and weight distribution in motion, with subsequent effects on coordination of movement (including limb interference), balance, power (propulsion, impulsion, and collection), agility, and endurance. 7. Veterinarian conformational assessment should particularly focus on the presence of any such faults and the relationship of these faults to existing or potential pathologic conditions (Rossdale and Butterfield, 2006). In the hindlimb, a plumb line dropped from the ischial tuberosity should touch the point of the calcaneous (prominent caudally in the tarsus or hock), follow the plantar metatarsal surface to the metatarsophalangeal joint (MTPJ or fetlock) and fall 7.5 to 10 cm caudal to the heel in the lateral view. As the horse ages, the proportion of white hair may increase but usually not to the extent this occurs in grey horses. The hindquarters influence the horses capacity for: The gaskin and thigh muscles power running, jumping and other forward movements. The literature presented in this chapter will follow the terminology appearing in the research papers. Here are five areas of concern that Dr. Morrow sees in rope horses that come through his practice regularly. Excessive bulk can cause soundness problems. subjective assessment precludes sole use of this method to compare results between studies or substantiate the more complex relationships among conformation, performance, and soundness. There is emerging a new way of assessing conformation in the dynamic realm, until now . However, certain conformational faults such as extreme tarsal angulation (large or small) and tarsal valgus are almost certainly predisposing to injury or lameness in racing events and are best avoided. Tibiotarsal (hock) angle 53 degrees or less (Holmstrom et al., 1990) Absorbs excess impact on medial (inner) limb structures. A horse can move best with a short back and long neck. A horse needs to be standing squarely and fully weight bearing on all 4 feet to properly evaluate static balance. . The walk and trot should be checked both under saddle and in hand. good conformation. However, this requires expensive equipment, has the health and safety implications of possible radiation exposure to personnel involved, and is very sensitive to subject positioning (Barr, 1994; White et al., 2008). The croup helps transfer energy for thrust and power from the hindquarters. (From Mawdsley A, Kelly EP, Smith FH, Brophy PO: Linear assessment of the thoroughbred horse: an approach to conformation evaluation, Equine Vet J 28:461, 1996.) Cow hocked/in at the hock Illustrations of some common conformational defects of the hooves (see Table 15-1 for description). The neck should tie into the horse's body fairly high with a distinct chest area below. Proximal end of the spine of the scapula, 4. This evaluation may be regarded as the front line for judgments when selecting horses for specific intended tasks, including breeding selection. 6. Conformation will, therefore, partially dictate the relationship between form and function, thus modifying the potential for biomechanical efficiency, superior performance, musculoskeletal durability, and perhaps even longevity (Wallin et al., 2001). Chin Groove: the part of the horse's head behind the lower lip and chin. Signs of dynamic imbalance are limb interference, toe first landing, and obvious medial or lateral landing, twisting or bowing of the limb when traveling in a straight . Straight behind Moreover, many polypeptides with widely varying amino acid sequences and folded states . It should be round with muscle to provide a smooth contoured shape. The lack of anatomic precision, documentation, or both limits the interpretation of some studies. Proximal end of the tuber coxae The conformation or inherent anatomic structure of the horse is an integral part of the equine musculoskeletal constitution and will influence the quality of dynamic performance. The denition of conformation can be articulated Fig 11.2 Standard position and reference points used in conformation analysis of Thoroughbred racehorses. Fatigue amplifies such busy limb motion, making the horse more likely to interfere (one foot hitting the other leg) in addition to adding impact more on one side of the hoof and limb than the other.. She cites an example of a horse with contracted heels or a. A nicely sloped hoof will transfer weight from the tendons to the upper leg. Ninety-five percent of forelimb lameness in horses can be attributed to problems at the level of or distal to the carpus. The Crest: the top part of the neck under the mane. And, armed with that knowledge, you can take steps to help keep him sound. From these observations, an overall proportioned symmetry in lengths and heights is desirable, both left to right and fore to hind. . Establishing the exact source of the alignment deviation is imperative; for example, does a laterally pointing hoof, commonly described as toed out, originate from an externally rotated limb or from a particular distal joint? Image: drfgyhjkl (image/png) Answer. Introduction. Natural Disaster: Are You and Your Horse Ready for Emergency Evacuation? Forward at the knee/bucked knee/over at the knee/sprung knee Notably, the definition and number of traits evaluated, the point scale scoring system of conformational traits, and the image of an ideal phenotype varies greatly among registries, organizations, and countries; therefore, specific classification is essential for comparative evaluations. Prepurchase recommendations and perceived animal value rest highly on this assessment. Visual appraisal of defined criteria (the outlines and axes described above) and manual palpation of specific bony landmarks have been the basis of assessment, giving the examiner multiple three-dimensional images over a period. Restriction of the Achilles tendon sheath leads to thoroughpin (stress on the DDFT, with puffiness in the web of the hock). 6. Horses that are "well-built" and "put together correctly" are often among the top achievers in their sport. Initial attempts to provide absolute values in conformation assessment have used the tools listed in Table 15-2 in combination with a reference marker system. Tibiotarsal angle >170 degrees (Marks, 2000), usually due to a more upright tibia A line dropped from the cranial aspect of the greater tubercle of the humerus (point of the shoulder) should bisect the forelimb in the cranial view. When evaluating the conformation of a horse, you should consider the following areas: balance, muscle, structural correctness, and breed and sex characteristics (Figure 1). Height at withers, back, and croupLength of head, body, limbsDepth of chestWidth of breast and pelvis TABLE 152 This horse can develop an overall lighter movement that reduces concussive force on the feet and limbs to mitigate the development of forelimb lameness resulting from poor hoof conformation., Riders in many disciplines desire certain neck sets and conformation that lead to musculoskeletal issues, says Collatos. Horses with limb deviations often dont travel with their legs staying in one planethey tend to wing in or wing out, Duberstein continues. Congruent sloping angulation of the shoulder and hip is also desirable, with a proportional length of individual limbs in relation to the height and size of the body (Figure 15-3). Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metatarsal bone Congruent sloping angulation of the shoulder and hip is also desirable, with a proportional length of individual limbs in relation to the height and size of the body (Figure 15-3). Horses are more likely to suffer a severe injury when they fatigue, says Duberstein. Front Leg Conformation. All rights reserved. Conformation of the cervical (neck) spine is critical for creating a connection from the poll to the base of the tail, she explains. Absorbs excess impact on lateral (outside) limb structures and increases pastern and coffin joint potential for osteoarthritis. This video gives a brief introduction to evaluating a horse's stride and overall evaluation.In this set of videos, Kathy Anderson and Libby Lugar provide inf. FIGURE 15-5 Illustrations of some common conformational defects of the hooves (see Table 15-1 for description). Nancy S. Loving, DVM, owns Loving Equine Clinic in Boulder, Colorado, However, the quan-tity and qual ity of the blending of these body parts determine the acceptability or unaccept-ability of the horse's conformation. A good farrier balances the horse, not just the foot., In horses with limb deviations, hoof angles tend to develop imbalances more quickly than horses with good limb conformation because the way the crooked leg moves causes uneven wear on the hoof, adds Duberstein. A visual appraisal of the horse at rest. For this reason both Collatos and Duberstein try to avoid limb conformation that might predispose a horse to suspensory ligament desmitis (SLD, inflammation of that structure), including straight hock conformation and long cannon bones and pasterns. Posted by Nancy S. Loving, DVM | Oct 19, 2021 | Breeding and Reproduction, Conformation Problems, Forelimb, Hindlimb, Hoof Problems, Horse Care, Lameness, Limb Anatomy & Physiology, Lower Limb, Other Conformation Topics, Sports Medicine. It affects the looks of a horse - the shape and proportions of its body. Radiocarpal joint angle >180 degrees or lack of full carpal extension causing a flexion moment The neck should tie into the horse's body fairly high to provide good chest space. Selecting a horse that is well-built in its skeletal structure will provide a more comfortable ride and reduce health issue. Also different from halter horses, are the cutting horses which are strictly bred for the ability to work a cow, whatever conformation may be the result. Twisting of fetlocks also predisposes to arthritis. When assessing foal conformation, limbs can also be viewed from above at the shoulder and hip (skyline view). . 2. Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metacarpal bone Illustrations of some common conformational defects of the forelimbs (see Table 15-1 for description). Figure 1 demonstrates this conformation. Designed by Elegant Themes | Powered by WordPress, You need to be logged in to fill out this form. Assessing limbs, feet, and body can help you and your veterinarian identify anatomical traits that could end up being performance-affecting liabilities. Conformation: The conformation of a horse refers to how the horse is built. In the hindlimb, a plumb line dropped from the ischial tuberosity should touch the point of the calcaneous (prominent caudally in the tarsus or hock), follow the plantar metatarsal surface to the metatarsophalangeal joint (MTPJ or fetlock), and fall 7.5 to 10 cm (Ross, 2003) caudal to the heel in the lateral view. Webcast | Dorsal edge of the coronary band Lack of symmetry will stress those points and may harm or limit the horses ability to perform with grace and ease. They generally appear somewhat uphill in their balance, with a neck that comes relatively high out of the withers, a moderately sloped shoulder, and a very powerful sacrum and pelvis. So, it is sensible to avoid conformational problems like being calf-kneed (back at the knee), which potentially exacerbates hyperextension of these joints. From foal to adult, horses can develop all sorts of leg alignment issues like pigeon-toed, bow-legged or knock-kneed in the front legs, and cow-hocked, sickle-hocked in the hind legs and many more. Initial attempts to provide absolute values in conformation assessment have used the tools listed in Table 15-2 in combination with a reference marker system. A horse should have well-formed withers where the shoulder can attach to the rest of the body. From the side of the front leg, a straight line should be formed in front of the withers down the center of the front leg and touch at the heel. The basics of horse conformation. A wide chest (from the front) allows for good stamina, endurance and lung capacity. The front legs support 60-65% of the horse's weight. Advancing technology has allowed more objective, quantitative evaluation of conformation amenable to statistical analysis and aims to find evidence-based relationships among conformation, performance, and soundness. Conformation will, therefore, partially dictate the relationship between form and function, thus modifying the potential for biomechanical efficiency, superior performance, musculoskeletal durability, and perhaps even longevity (Wallin et al., 2001). Conformation can be defined as the formation of something by appropriate arrangement of parts or elements: an assembling into a whole (Websters dictionary, 1976) and equine conformation appraisal is traditionally based on the external appearance of the body shape, form or outline of the animal. Figure 1. A strong, well-placed hock makes a stronger, more efficient leg. Shortened, choppy stride with potential to stumble. "A long or short neck may affect the way the horse rides but it will . Therefore, Quarter Horse conformation tends to be downhill with tremendous power and musculature in the sacrum, hips, and thighs to enable them to dig in, turn, and go. The neck should tie into the horse's body fairly high to provide good chest space. highlighting the importance of standardized repeatable positioning of the horse. are bred to work cattle, and a lower headset facilitates rapid turns with exceptional speed and quickness from the hindquarters. Beauty is in the eye of the beholder. Cranial, caudal, and lateral views are needed to determine limb deviations in the sagittal, coronal (frontal), and transverse planes (see Figures 15-1 and 15-2). Dynamic load distribution and landing patterns play an important role in equine orthopaedics. Briefly, relevant body observations should include head shape and size; height at the withers and croup; body length; neck length; shoulder length (top of the withers to point of the shoulder); pelvic length (tuber coxae to tuber ischii); scapular and humeral inclination; pelvic and femoral inclination; and chest width. Judging and Conformation of Horses By: Carey Williams, Ph.D. - Rutgers University Graphics courtesy of: US Pony Club Manual of Horsemanship Book 1 Balance 1. Dynamic conformation. However, (such) a horse may have conformational characteristics that are able to be trained for maximum locomotor efficiency, such as the ability to move with impulsion from behind, raise its withers, and engage its core. A good first step is to work with a competent farrier to maintain a regular trimming and shoeing schedule that ensures keeping a horses hoof angles as correct as possible for that individual.. To have the best chance of a sound horse, first select one with good all-around conformation, keep hoof angles balanced, maintain the horse at a healthy weight to avoid overtaxing the musculoskeletal system, provide plenty of turnout, and condition him properly to do the job you are going to ask him to do, says Duberstein. Center of the anterior part of the greater trochanter of the femur, 3. A horse that has horizontal balance will have a straight line from withers to croup. The success of a horse in any equine discipline or industry is not dependent on perfect conformation, as this does not guarantee performance or soundness, and imperfect conformation does not necessarily exclude a horse from performing at elite levels. When assessing deviation of the limb from the vertical, Weller et al. Back at the knee/calf knee What movement defect is this due to bad conformation? A shorter hindquarter supports power and strength. Long or short neck. While theres no such thing as perfect conformation, certain structural qualities and alignments are more likely to support soundness than others. Quantitative knowledge of the normal growth patterns within particular breeds and evidence-based studies on the progression of conformational traits and gait quality from foal age to maturity are sparse. In the growing horse, trimming and shoeing can have a huge influence on the growth and development of the bony column. A balanced and proportionate body is key to proper leg structure. The lack of anatomic precision, documentation, or both limits the interpretation of some studies. However, training can help develop core strength and flexibility to markedly enhance a horse with less-than-ideal balance or limb conformation. Characteristics of hoof conformation in feral horses have been used to question this concept. In the hindlimb, a plumb line dropped from the ischial tuberosity should touch the point of the calcaneous (prominent caudally in the tarsus or hock), follow the plantar metatarsal surface to the metatarsophalangeal joint (MTPJ or fetlock) and fall 7.5 to 10 cm caudal to the heel in the lateral view. The segment lengths of specific long bones of limbs should also be noted at this time. A line dropped from the cranial aspect of the greater tubercle of the humerus (point of the shoulder) should bisect the forelimb in the cranial view. For these, quantitative conformational assessment, in addition to these traditional judging methods, has been suggested to improve predictive capability (Holmstrom and Philipsson, 1993). In horses with ideal conformation, a visualized vertical plumb line dropped from the tuberosity of the scapular spine should bisect the longitudinal axis of the forelimb to the metacarpophalangeal joint (MCPJ or fetlock) and fall 5 cm behind the heel in the lateral view. When you choose a horse (or choose a career for a horse you have), says Collatos, consider your athletic pursuit and how the horses conformation will affect his ability to perform in that endeavor: Overall balance and locomotor efficiency are extremely important to a horses athletic longevity and ability to compensate for lower-limb defects, says Collatos. The segment lengths of specific long bones of limbs should also be noted at this time. Objective assessment of conformation Distance between the forelimbs is greater at the chest than feet, the limb sloping medially Her book, All Horse Systems Go, is a comprehensive veterinary care and conditioning resource in full color that covers all facets of horse care. Conform ation analysis is the system atic com parison of one horse to another, and all horses to an ideal type for the breed or athletic pu rpose. Aesthetic factors such as athletic elegance, suppleness, overall balance and harmony, jumping style, and movement symmetry are necessarily subjectively based. Conformation refers to the structure or outline of an animal as determined by the arrangement of its parts. , as the ultimate long-distance athletes, are generally balanced front to back, with lean muscle mass and shoulder angles that optimize efficiency at moving across the ground with minimal effort or limb lift. The absence of standardized evaluation standards, lack of centralized training programs internationally, and a large source of error introduced by subjective assessment precludes sole use of this method to compare results between studies or substantiate the more complex relationships among conformation, performance, and soundness. The head should meet the neck at an angle so the horse can flex at the pole and move in balance. CHAPTER 15 This includes Bute or Banamine, etc. Having these traits provides a balanced head and neck. Anatomic Description of Commonly Used Conformational Terms, FIGURE 15-1 Illustrations of some common conformational defects of the forelimbs (see Table 15-1 for description). Ideally, when viewed from the side, you should be able to draw a straight line through the center of the bones of the forearm, knee, cannon and bulb of the heel. 3. Good conformation is the foundation for good performance. Either a rotational change in the hindlimb or tarsus valgus >180 degrees Sickle hock/curby hock The stance of the horse has been identified as a major source of error in conformation assessment, as small changes in limb placement and weight distribution can introduce significant variation in segmental alignment. Height at withersLength of croup and backWidth of chest and mandibleCircumference of girth; neck at poll and withers (Mawdsley et al., 1996); carpus; the third metacarpal/metatarsal; girth No one recipe applies to every horseyoull need to work with your farrier to tailor your horses foot care to his individual conformation and way of going. Riders often have the objective of lightening a horses front end under saddle by spending time worrying about head position, says Duberstein. Establishing the exact source of the alignment deviation is imperative; for example, does a laterally pointing hoof, commonly described as toed out, originate from an externally rotated limb or from a particular distal joint? Racehorse conformation and its' potential to predict animal performance - Volume 2009 Initial attempts to provide absolute values in conformation assessment have used the tools listed in Table 15-2 in combination with a reference marker system. Weller et al. Good basic conformation is the answer! Why were losing our horse doctors and how to begin solving the problem. The veterinarian palpates the horse, checking muscles, joints, bones and tendons for evidence of pain, heat, swelling or any other physical abnormalities. These traits were hoofpastern axis in both forelimbs and hindlimbs, head size, and vertical alignment of the forelimbs and hindlimbs, all having a coefficient of variation greater than 10%. Particular attention is warranted in evaluation of distal limb alignment, hoof quality, size, and balance due to the concentration of locomotive stresses in this area. Biomechanical evaluation relies heavily on strict physical and mechanical relationships of segments, requiring accurate anatomic terminology. Inward rotation of the hocks leads to osteoarthritis and thoroughpin. Prior to a veterinarian's examination to diagnose the causes of lameness, the horse should be off any pain medications for at least 24 hours. The sacral spines are labeled S1 to S5 and the green line shows the croup angle. The ideal horse will probably grow and wear its feet down evenly because it will properly load its weight when it moves. TABLE 151 Correct front legs will move in a straight line and promote the following. Pigeon Toe-ed or Toe-ed Out Horses. 2023 3. Briefly, relevant body observations should include head shape and size; height at the withers and croup; body length; neck length; shoulder length (top of the withers to point of the shoulder); pelvic length (tuber coxae to tuber ischii); scapular and humeral inclination; pelvic and femoral inclination; and chest width. (2006a) found measurement variations in stance within one horse to be almost as large as between horses, thus. FIGURE 15-4 In horses with ideal conformation, a visualized vertical plumb line dropped from the tuberosity of the scapular spine should bisect the longitudinal axis of the forelimb to the metacarpophalangeal joint (fetlock) and fall 5 cm behind the heel in the lateral view. Hindlimb Strain on inner hock joint structures predisposes to osteoarthritis. The constant growth of the hoof creates a dynamic relationship between the digital axis and dorsal hoof wall, which suggests that completely straight hoofpastern axes cannot exist over time without natural wear or appropriate trimming (Moleman et al., 2006). Whether barefoot or shod, the resilience to withstand the stresses of competition and to achieve athletic longevity is enhanced by a balanced foot, says Collatos. As some conformational traits are dynamic and will only be apparent during ambulation, the traditional emphasis of conformational assessment as a pure description of static external appearance has been extended to include a more functional assessment of conformation during unridden and ridden gaits in some of the studies cited in this chapter.
